Exclamation After water damage, car cranks but gears won't shift af

I had some water leaking which bot worse when the GL lost it completely. The cars was self opening and closing back doors windows, honking, activating the front wipers, .... until there is no more battery.
I got the battery charged, the car dry and even changed the auxiliary battery. But the car does not move. It cranks normally but even though it shows on the screan that the gearg are shifting nothing is happeneing and the car is not moving when giving gases...
Please help I don't know what to do? I have seen youtube videos explaining how to reset the TCM, or about the ISM, ...
I don't know what to do. PLEASE help.

I am sorry that car is toast. You can try to dry out all the electronics as best you can but ultimately they will fail in spectacular fashion again.
